For most people, “infrared technology” calls to mind the night vision goggles from classic spy movies, providing blurry heat signature images of enemy guards on nighttime patrol. In reality, the scope of infrared technology has expanded well past night vision goggles to encompass a broad spectrum of sophisticated applications. Today, sensors around ship ports use night vision technology to keep an eye out after dark. Satellites use infrared technology to look out further into space. And these advanced sensors have distance capabilities far surpassing those movie goggles that saw to the other end of the room. Current infrared equipment can peer out for miles into the dark.
